Thermal Consideration Thermal Consideration The power module operates in a variety of thermal environments; however, sufficient cooling should be provided to help ensure reliable operation of the unit. Heat is removed by conduction, convention, and radiation to the surrounding environment. Proper cooling can be verified by measuring the case temperature. The case temperature (Tc) should be measured at the position indicated see figure below. The temperature at this location should not exceed 100°C. When operating the power module, adequate cooling must be provided to maintain the power module case temperature at or below 100°C. Although the maximum case temperature of the power modules is 100°C, you can limit this temperature to a lower value for extremely high reliability. Optimum cooling is obtained with forced convention. Some typical thermal resistance numbers are tabulated below: Thermal resistance vs. air flow chart

Output over current protection When excessive output currents occur in the system, circuit protection is required on all power supplies. Normally, overload current is maintained at approximately 115~150 percent of rated current for TEN 40. Hiccup-mode is a method of operation in a power supply whose purpose is to protect the power supply from being damaged during an over-current fault condition. It also enables the power supply to restart when the fault is removed. There are other ways of protecting the power supply when it is over-loaded, such as the maximum current limiting or current foldback methods. One of the problems resulting from over current is that excessive heat may be generated in power devices; especially MOSFET and Shottky diodes and the temperature of those devices may exceed their specified limits. A protection mechanism has to be used to prevent those power devices from being damaged. The operation of hiccup is as follows. When the current sense circuit sees an over-current event, the controller shuts off the power supply for a given time and then tries to start up the power supply again. If the over-load condition has been removed, the power supply will start up and operate normally; otherwise, the controller will see another over-current event and shut off the power supply again, repeating the previous cycle. Hiccup operation has none of the drawbacks of the other two protection methods, although its circuit is more complicated because it requires a timing circuit. The excess heat due to overload lasts for only a short duration in the hiccup cycle, hence the junction temperature of the power devices is much lower. The hiccup operation can be done in various ways. For example, one can start hiccup operation any time an over-current event is detected; or prohibit hiccup during a designated start-up is usually larger than during normal operation and it is easier for an over-current event is detected; or prohibit hiccup during a designated start-up interval (usually a few milliseconds). The reason for the latter operation is that during start-up, the power supply needs to provide extra current to charge up the output capacitor. Thus the current demand during start-up is usually larger than during normal operation and it is easier for an over-current event to occur. If the power supply starts to hiccup once there is an over-current, it might never start up successfully. Hiccup mode protection will give the best protection for a power supply against over current situations, since it will limit the average current to the load at a low level, so reducing power dissipation and case temperature in the power devices.
Short Circuitry Protection Continuous, hiccup and auto-recovery mode. During short circuit, converter still shut down. The average current during this condition will be very low and the device can be safety in this condition.
Input Source Impedance The power module should be connected to a low impedance input source. Highly inductive source impedance can affect the stability of the power module. Input external L-C filter is recommended to minimize input reflected ripple current. The inductor is simulated source impedance of 12μH and capacitor is Nippon chemi-con KZE series 47μF/100V. The capacitor must as close as possible to the input terminals of the power module for lower impedance.
Over Temperature Protection The power modules operate in a variety of thermal environments; However, sufficient cooling should always be provided to help ensure reliable operation. The over-temperature protection consists of circuitry that provides protection from thermal damage. If the temperature exceeds the over-temperature Threshold the module will shut down. For reliable operation this temperature should not exceed 100 the output power of the module should not exceed the rated power of the module

Safety and Installation Instruction Isolation consideration The TEN 40 series features 1.6k Volt DC isolation from input to output, input to case, and output to case. The input to output resistance is greater than 109 megohms. Nevertheless, if the system using the power module needs to receive safety agency approval, certain rules must be followed in the design of the system using the model. In particular, all of the creepage and clearance requirements of the end-use safety requirement must be observed. These documents include UL-1950, EN60950 and CSA 22.2-950, although specific applications may have other or additional requirements. Fusing Consideration Caution: This power module is not internally fused. An input line fuse must always be used. This encapsulated power module can be used in a wide variety of applications, ranging from simple stand-alone operation to an integrated part of a sophisticated power architecture. To maximum flexibility, internal fusing is not included; however, to achieve maximum safety and system protection, always use an input line fuse. The safety agencies require a normal-blow fuse with maximum rating of 5 A. Based on the information provided in this data sheet on inrush energy and maximum dc input current, the same type of fuse with lower rating can be used. Refer to the fuse manufacturer’s data for further information.
MTBF and Reliability The MTBF of TEN 40 series of DC/DC converters has been calculated using The MTBF of TEN 40 series of DC/DC converters has been calculated using 1. MIL-HDBK-217F under the following conditions:
Nominal Input Voltage Iout = Iout max TA = 25°C
The resulting figure for MTBF is 292’400 hours single and dual output. The resulting figure for MTBF is 364’600 hours triple output.
2. Bellcore TR-NWT-000332 Case I: 50% stress, Operating Temperature at 40°C (Ground fixed and controlled environment) The resulting figure for MTBF is 1’398’000 hours.
